Any Ideas what this could be and how I can solve the Problem?

Many thanks,

Chris.

This is a Burner Bass? Made in 1989? If so, the first batch of 40 basses did this. They were corrected by the second batch a few months later.

Other than that, you might just need a new circuit being that this is a 20 year old bass. Not a huge expense considering its age. I wish my Car ran as well or any car for that matter.
